Forget Credit Cards; PayTango Lets You Pay by Fingerprint

The idea is simple (and absolutely terrifying): Take your fingerprints, upload them to a database somewhere, then have that information connected to whatever mode of payment you so desire.

Pow–just scan your fingerprint to pay. You’ll never have to worry about whether you’ve brought sufficient cash or have the right credit cards again.

As is often the case with cool new start-ups revolving around unusual ideas, the people responsible for PayTango are not, in fact, seasoned veterans of the field, but are instead four students from Carnegie Mellon University.
